Dupe Bug Causes ESO Bank Closures

The use of Guild Banks has been suspended in
The Elder Scrolls Online due to
an economy-endangering item duplication bug, according to
PC Gamer, noting that some users are complaining that they've been trying to
bring the matter to the attention of Bethesda Softworks for weeks. There is
apparently a patch in the works, and they have a statement from Bethesda, where
they are taking a hard line on this:

Yesterday, we identified an item
duping bug in ESO that some players chose to exploit. We acted quickly, and have
since fixed the issue. We have a zero tolerance policy when it comes to abusing
exploitable bugs, and those who were found doing so will have their game account
permanently banned.
